Bron, My Cyrus is from RPM, and I am just nursing it along until my users finish migrating off and FastMail manages to complete my own migration, so I don't want to build from source. Why would IMAP/S block on empty /dev/random, while IMAP+STARTTLS works? FWIW, SASL2 seems to use urandom. > [root@inspector random]# strings /usr/lib/libsasl* |grep random > /dev/urandom > /dev/urandom But my /dev/random does seem quite low. Still surfing and looking for a good way to fill it on a mostly headless server -- I haven't found a good solution yet.
